Description

本発明は、請求項１の上位概念に記載の車両座席に関する。  The present invention relates to a vehicle seat according to the superordinate concept of claim 1.

このような車両はドイツ連邦共和国特許出願公開第１０２００４０４４３６３号明細書から公知であり、縦方向に調節可能な座部分とこれに枢着される背もたれとを持っている。直立する使用位置で、係止調節器を介して鎖錠される背もたれ又はその背もたれ枠は、一般に快適揺動範囲内で傾斜調節可能である。係止調節器の釈放後、背もたれは前方へ折り畳み可能である。このため使用者は、一般に操作ハンドル例えば背もたれ軸線の周りに揺動可能な解錠レバーを操作するので、背もたれ又はその背もたれ枠は、続いて快適揺動範囲を越えて前方へ、例えばテーブル位置として又はその後にある荷物室を大きくするための貨物位置として又は他の目的のためにも役立つ水平な機能位置へ、折り畳まれる。前方へ折り畳まれる貨物位置から始まって、更に若干の車両座席では、車両座席を前部揺動軸線の周りにせき止め位置又は巻き付け位置へ前方揺動させるため、後部脚が釈放可能である。しかしこの場合使用される装置は一般に費用がかかる。  Such a vehicle is known from DE 102004044363 A1 and has a longitudinally adjustable seat part and a backrest pivoted on it. In the upright use position, the backrest or the backrest frame that is locked via the locking adjuster is generally adjustable in inclination within a comfortable swing range. After release of the locking adjuster, the backrest can be folded forward. For this reason, the user generally operates an operation handle such as an unlocking lever that can be swung around a backrest axis, so that the backrest or its backrest frame is subsequently moved forward beyond the comfortable swing range, for example, as a table position. Or it can be folded into a horizontal functional position that serves as a cargo position to enlarge the subsequent luggage compartment or for other purposes. Starting from a cargo position that is folded forward, in some further vehicle seats, the rear legs can be released in order to swing the vehicle seat forward around the front swing axis to a damped or wrapped position. However, the equipment used in this case is generally expensive.

種々の調節のために、適当なハンドル、例えば快適揺動範囲内で背もたれの傾斜を調節する操作レバー、係止調節器を解錠する容易立入りハンドル、及び場合によっては後部鎖錠装置を釈放するハンドルが設けられている。使用者が機能位置以外で後部鎖錠装置を釈放する場合、一般に続いてせき止め位置が得られないので、車両座席を場合によってはまず再び戻り調節せねばならない。従って使用位置からの不当な解錠を回避するため、付加的な連結機構が設けられている。  For various adjustments, release appropriate handles, such as operating levers that adjust the tilt of the backrest within the comfortable swing range, easy-access handles to unlock the locking adjusters, and possibly rear locking devices A handle is provided. If the user releases the rear locking device in a position other than the functional position, it is generally not possible to obtain a subsequent stop position, so that the vehicle seat must first be returned and adjusted in some cases. Therefore, an additional coupling mechanism is provided to avoid unauthorized unlocking from the use position.

ドイツ連邦共和国における国際公開特許のドイツ語翻訳第６９９１９３５９号は、折り畳み及び折り返し可能な車両座席を示し、後部座席の後部脚が解錠された後、後部座席がせき止め位置へ調節可能である。この場合後部脚と前部脚との連結は機構を介して行われるが、この機構は比較的複雑であり、従って費用がかかる。  German translation 69913959 of the internationally published patent in the German Federal Republic shows a vehicle seat that can be folded and folded back, and after the rear leg of the rear seat is unlocked, the rear seat can be adjusted to a damped position. In this case, the connection between the rear leg and the front leg is made via a mechanism, which is relatively complex and therefore expensive.

米国特許第６，８８３，８６８号明細書は、背もたれ折り畳みと縦方向調節を可能にする車両座席を示している。ドイツ連邦共和国特許第１９９１８７８５号明細書は、背もたれの折り畳みと脚の解錠を可能にする車両座席用金具を示している。この場合金具の下部は、すわり位置において戻り止め爪により車両構造において鎖錠し、下部に対して回転可能な上部が背もたれに結合されている。更に上部を座席の包装位置に確保する安全レバーと、戻り止め爪及び安全レバーとは無関係な付加安全装置が設けられている。  U.S. Pat. No. 6,883,868 shows a vehicle seat that allows for backrest folding and longitudinal adjustment. DE 199 18 785 shows a vehicle seat fitting which allows folding of the backrest and unlocking of the legs. In this case, the lower part of the metal fitting is locked in the vehicle structure by a detent claw at the sitting position, and the upper part rotatable relative to the lower part is coupled to the backrest. Furthermore, a safety lever that secures the upper portion of the seat in the packaging position and an additional safety device that is independent of the detent pawl and the safety lever are provided.

ドイツ連邦共和国特許第１９５１４３８０号明細書は、釈放可能に鎖錠される後部脚及び拘束可能な継手金具を介して座枠に結合される背もたれを持つ座枠を有する車両座席を示し、背もたれは機能位置へ前方に折り畳み可能である。この場合背もたれが前方へ折り畳まれる機能位置にある時にのみ、脚が釈放可能である。ここに示されている機構も同様に複雑で費用がかかる。  German Patent No. 19514380 shows a vehicle seat having a seat frame with a back leg that is releasably locked and a back frame that is coupled to the seat frame via a constraining fitting. Can be folded forward into position. In this case, the legs can only be released when the backrest is in a functional position where it can be folded forward. The mechanism shown here is similarly complex and expensive.

本発明の基礎になっている課題は、比較的簡単な構造で多面的な調節を可能にする車両座席を提供することである。  The problem underlying the present invention is to provide a vehicle seat which allows a multi-faceted adjustment with a relatively simple structure.

この課題は、請求項１に記載の車両座席によって解決される。従属請求項は好ましい展開を記載している。  This problem is solved by the vehicle seat according to claim 1. The dependent claims describe preferred developments.

本発明の基礎になっている考えは、座枠（座部分、座クッション支持体、座架台）の両方の後部鎖錠装置を互いに無関係に又は別々に釈放又は解錠することである。この場合これらの両方の解錠過程は種々の調節の際行われる。  The idea on which the present invention is based is to release or unlock both rear locking devices of the seat frame (seat part, seat cushion support, pedestal) independently of one another or separately. In this case, both of these unlocking processes are performed during various adjustments.

座枠の両方の鎖錠装置（後部脚）は、特に車両シャシの構造部分またはシャシ側下部レールに対して移動可能な上部レールであってもよい構造部分において鎖錠する。  Both locking devices (rear legs) of the seat frame lock in particular in the structural part which may be the structural part of the vehicle chassis or the upper rail which is movable relative to the chassis side lower rail.

本発明によれば、鎖錠装置の一方が、操作装置特にハンドルにより直接釈放され、他方の鎖錠装置が、これとは別々に、別の操作装置によるか又は特に座素子の調節によっても釈放される。このような構成は、直立する使用位置、背もたれと座枠との間に設けられる自由揺動装置（特に係止調節器ただし例えば伝動金具）の解錠及び背もたれの前方折り畳み後に得られる機能位置（テーブル位置）、及び前部揺動軸の周りにおける座席全体の前方揺動により得られるせき止め位置又は巻付け位置を持つ車両座席のために重要である。使用者は、操作装置例えば揺動可能なハンドルにより、座枠にある背もたれの自由揺動装置を釈放でき、これにより両方の後部鎖錠装置の一方が釈放されることはない。続いて背もたれの前方折り畳みの際、その折り畳み運動が第１の鎖錠装置を釈放できるので、この機能位置にある車両座席が、最初のうち他方の鎖錠装置によりまだ鎖錠されている。  According to the invention, one of the locking devices is released directly by the operating device, in particular the handle, and the other locking device is released separately from this by another operating device or in particular by adjusting the seat element. Is done. Such a configuration includes an upright use position, a functional position obtained after unlocking a free swinging device (particularly a locking adjuster, for example, a transmission fitting) provided between the backrest and the seat frame and folding the backrest forward. Table position) and for vehicle seats with a damming or wrapping position obtained by a forward swing of the entire seat around the front swing axis. The user can release the free swing device of the backrest in the seat frame by means of an operating device, for example a swingable handle, so that one of both rear locking devices is not released. Subsequently, when the backrest is folded forward, the folding movement can release the first locking device, so that the vehicle seat in this functional position is initially locked by the other locking device.

この基礎になっている認識は、前方へ折り畳まれる機能位置におけるこの非対称な片側解錠が原則的に危険でないということである。なぜならば、座席は使用者を受入れておらず、座席の僅かな負荷のため、衝突の場合にも危険が起こらないからである。使用者は機能位置から次に他方の鎖錠装置を釈放できるので、車両座席を前方へせき止め位置へ前方揺動させることができる。  The underlying recognition is that this asymmetric one-side unlocking in the functional position folded forward is in principle not dangerous. This is because the seat does not accept the user, and because of the slight load on the seat, there is no danger in the event of a collision. Since the user can then release the other locking device from the functional position, the vehicle seat can be swung forward to the damming position.

この場合本発明によれば、１つの操作装置のみにより、特にただ１つのハンドルにより、特に多面的な調節が可能である。この場合ハンドル例えば背もたれ軸線の周りに揺動可能な操作レバーは、一方では自由揺動装置の釈放のために、また他方では機能位置から次にせき止め位置への座席の前方揺動のため第２の鎖錠装置の釈放のために利用される。  In this case, according to the invention, a multifaceted adjustment is possible with only one operating device, in particular with a single handle. In this case, a handle, for example an operating lever which can be swung around the backrest axis, is used on the one hand for releasing the free swiveling device and on the other hand for swiveling the seat forward from the functional position to the next blocking position. Used for the release of the locking device.

本発明によれば、ハンドルのそのつどの操作の際、意図しない調節を開始しないために、連行装置を有利に設けることができる。連行装置は、例えば適当な行程を持つ長穴−ピン継手として構成することができる。このような継手は、特に背もたれ枠と一方の鎖錠装置との間に、更にハンドルと他方の鎖錠装置との間、及び操作ハンドルと自由揺動装置を解錠する解錠レバーとの間にも設けることができる。  According to the invention, an entrainment device can advantageously be provided in order not to initiate unintended adjustments during each operation of the handle. The entrainment device can be configured, for example, as a long hole-pin joint having an appropriate stroke. Such joints are particularly between the back frame and one locking device, between the handle and the other locking device, and between the operating handle and the unlocking lever that unlocks the free swing device. Can also be provided.

添付図面により本発明の実施例が以下に説明される。  Embodiments of the present invention will be described below with reference to the accompanying drawings.

車両座席１は座枠２及び背もたれ枠３を持っている。この場合車両座席のうち、クッション及び張り布なしの構造部分又は枠部分のみが示されている。座枠２（座部分、座クッション支持体）と背もたれ枠３との間で左側及び右側に、自由揺動装置としてそれぞれ１つの係止調節器４が設けられて、図１に示す直立した使用位置における背もたれ枠３の拘束を可能にし、この使用位置で一般に背もたれの傾斜調節が、快適範囲内で可能である。両方の係止調節器４の解錠後、背もたれ枠３を背もたれ軸線Ａの周りに前方へ、図２に示す機能位置特にテーブル位置へ、折り畳むことができる。両方の係止調節器４は、解錠軸５を介して互いに結合され、一般に鎖錠位置へばねの予荷重を受けている。  The vehicle seat 1 has a seat frame 2 and a backrest frame 3. In this case, of the vehicle seat, only the structural part or the frame part without the cushion and the upholstery is shown. 1 is provided on the left side and the right side between the seat frame 2 (seat part, seat cushion support) and the back frame 3 as free swinging devices, respectively, and is used upright as shown in FIG. The back frame 3 can be restrained at the position, and the inclination of the backrest can be generally adjusted within the comfort range at this use position. After unlocking both locking adjusters 4, the backrest frame 3 can be folded forward around the backrest axis A, to the functional position shown in FIG. Both locking adjusters 4 are connected to each other via an unlocking shaft 5 and are generally subjected to a spring preload to the locked position.

背もたれ枠３の（走行方向において）後ろの左側範囲で、左側の鎖錠装置としての鎖錠かぎ６が、揺動継手７に枢着されている。同様に座枠２の後ろ右側で、右側の鎖錠かぎ８が揺動継手９に枢着されている。鎖錠かぎ６及び８は、図１に示すように、特にシャシ側のピンであってもよい構造部分１０，１１において鎖錠を行う。即ち車両座席１全体が補足的に縦方向に調節可能に上部レール上に取付けられ、この上部レールがシャシ側下部レールに対して縦方向に調節可能である場合、構造部分１０，１１は上部レールに設けられている。有利なように鎖錠かぎ６，８は前方へ開いており、（図１において）時計方向への揺動運動により鎖錠を行う。この場合鎖錠かぎ６，８は、図１に示す鎖錠位置へばねの予荷重をかけられている。  A lock key 6 as a lock device on the left side is pivotally attached to the swing joint 7 in the left range behind the back frame 3 (in the traveling direction). Similarly, on the right side behind the seat frame 2, a right locking key 8 is pivotally attached to the swing joint 9. As shown in FIG. 1, the lock keys 6 and 8 lock the structure portions 10 and 11 which may be pins on the chassis side. That is, when the entire vehicle seat 1 is mounted on the upper rail so as to be supplementally adjustable in the vertical direction, and the upper rail is adjustable in the vertical direction with respect to the lower rail on the chassis side, the structural parts 10 and 11 Is provided. Advantageously, the lock keys 6, 8 are open forward and are locked by a rocking movement in the clockwise direction (in FIG. 1). In this case, the lock keys 6, 8 are preloaded with springs to the lock position shown in FIG.

係止調節器４を解錠するため、例えば一方の側例えば図１ないし３において座席の左側のみに設けられて解錠軸５に固定的に結合されかつ背もたれ軸線Ａの周りに揺動可能な解錠レバー１２が上方へ揺動される。解錠レバー１２から第１のピン１４が軸線方向に突出して、背もたれ軸線Ａの周りに揺動可能に支持される操作レバー１６の弧状長穴１５内に案内されている。従って弧状長穴１５とその中に案内されるピン１４は第１の連行機構として作用し、長穴１５は第１のピン１４に対する空動き行程（むだ行程）を規定し、この空動き行程内では、解錠レバー１２はまだ揺動されない。To unlock the locking adjuster 4, for example swingable about a fixedly coupled only to the unlocking shaft 5 is provided on the left side of one seat in the side for example 1 to 3 and back axis A unlocking lever 12 is swung upwards. From unlocking lever 12 first pin 14 projecting in the axial direction, is guided in an arcuate slot 15 of the operating lever 16 is swingably supported around the back axis A. Accordingly, the arc-shaped elongated hole 15 and the pin 14 guided therein act as a first entrainment mechanism, and the elongated hole 15 defines a lost movement stroke (dead stroke) with respect to the first pin 14 and is included in the lost movement stroke. In not unlock lever 12 Hamada swing.

左側の鎖錠かぎ６において、鎖錠かぎ６の揺動軸線を形成する揺動継手外にある継手１９に、連結棒１８が枢着されている。連結棒１８の上端には第２の長穴２０が形成され、操作レバー１６の後部範囲において軸線方向に突出する第２のピン２１が、この長穴２０内に案内されている。同様に右側の鎖錠かぎ８において、右側の連結棒２２が、揺動継手９外にある継手２３に枢着され、右側の連結棒２２も同様に上方へ延びて、その上部範囲に第３の長穴２４を持っている。第３の長穴２４には第３のピン２５が案内されているが、左側とは異なり背もたれ枠３に設けられ、そこで軸線方向に突出している。長穴２０及び２４は原則的に直線的に又は例えば少し湾曲して形成されている。重要なことは、これらの長穴がそれぞれのピン２１，２５の調節行程を空動き行程又はむだ行程として許容し、続いてそれぞれの鎖錠かぎ６，８の調節を可能にすることだけである。長穴−ピン組合わせとは異なる連行機構も可能である。  In the left lock key 6, a connecting rod 18 is pivotally attached to a joint 19 outside the swing joint that forms the swing axis of the lock key 6. A second long hole 20 is formed at the upper end of the connecting rod 18, and a second pin 21 protruding in the axial direction in the rear region of the operation lever 16 is guided into the long hole 20. Similarly, in the right lock key 8, the right connecting rod 22 is pivotally attached to the joint 23 outside the swing joint 9, and the right connecting rod 22 also extends upward in the upper range, so It has a long hole 24. A third pin 25 is guided in the third elongated hole 24, but is provided on the backrest frame 3, unlike the left side, and protrudes in the axial direction there. The long holes 20 and 24 are in principle formed linearly or, for example, slightly curved. All that is important is that these slots allow the adjustment stroke of the respective pins 21 and 25 as idle or dead strokes and subsequently allow adjustment of the respective locking keys 6 and 8. . An entrainment mechanism different from the long hole-pin combination is also possible.

背もたれ枠３は、その前端において、せき止め軸線（転倒軸線）Ｂの周りに揺動可能に支持されている。せき止め軸線Ｂは、車両シャシの構造部分又は場合によっては（縦方向調節可能な場合）シャシ側下部レールに対して縦方向調節可能な上部レールに形成されている。従ってせき止め軸線Ｂの周りにおける車両座席１の揺動は、両方の鎖錠かぎ６，８の解錠後に初めて可能である。  The back frame 3 is supported at the front end thereof so as to be swingable around a damming axis (falling axis) B. The damming axis B is formed on the structural part of the vehicle chassis or in some cases (if adjustable in the vertical direction) on the upper rail which can be adjusted in the vertical direction relative to the chassis side lower rail. Therefore, the swing of the vehicle seat 1 around the damming axis B is possible only after the unlocking locks 6, 8 are unlocked.

図１は、座枠２において鎖錠される背もたれ枠３が直立している車両座席の使用位置を示している。鎖錠かぎ６，８は構造部分１０，１１に鎖錠されている。図１では、解錠レバー１２の第１のピン１４は第１の長穴１５の下部ストッパ１５．１の所にあり、操作レバー１６に設けられる第２のピン２１は、第２の長穴２０の上部ストッパ２０．１の所にある。背もたれ枠３に設けられる第３のピン２５は、図１において第３の長穴２４下部ストッパ２４．１の所にあり、従ってそれは背もたれ枠３の最も後の快適位置に相当する。背もたれ枠３の快適揺動範囲内で、背もたれ枠３に設けられる第３のピン２５は、第３の長穴２４内に留まり、右側の連結棒２２を動かさないので、右側の鎖錠かぎ８は揺動されない。  FIG. 1 shows a use position of a vehicle seat in which a backrest frame 3 locked in the seat frame 2 stands upright. Locking keys 6 and 8 are locked to the structural parts 10 and 11. In FIG. 1, the first pin 14 of the unlocking lever 12 is located at the lower stopper 15.1 of the first elongated hole 15, and the second pin 21 provided on the operation lever 16 is the second elongated hole. 20 at the top stopper 20.1. The third pin 25 provided on the backrest frame 3 is located at the lower slot 24.1 of the third slot 24 in FIG. 1, and therefore it corresponds to the most comfortable position of the backrest frame 3. Within the comfortable swing range of the back frame 3, the third pin 25 provided on the back frame 3 stays in the third long hole 24 and does not move the right connecting rod 22. Is not rocked.

図１の鎖錠される使用位置から図２前方へ折り畳まれる機能位置へ車両座席を調節するため使用者はまず操作レバー１６を上方へ揺動するので、解錠レバー１２のピン１４が第１の長穴１５の下部ストッパ１５．１により連行され、従って解錠レバー１２が、解錠軸５を介して結合されている係止調節器４を解錠する。この場合操作レバー１６のピン２１は、第２の長穴２０内で上部ストッパ２０．１から下方へ、左側の連結棒１８を動かすことなく下部ストッパ２０．２へ達し、それにより解錠レバー１２の揺動運動が限定される。この解錠の際背もたれ枠３はまで調節されないので、第３の長穴−ピン継手２４，２５は最初のうち関係していない。  In order to adjust the vehicle seat from the locked use position shown in FIG. 1 to the functional position folded forward in FIG. 2, the user first swings the operating lever 16 upward, so that the pin 14 of the unlocking lever 12 is the first. The unlocking lever 12 is unlocked by the lower stopper 15.1 of the elongated hole 15 so that the unlocking lever 12 is connected via the unlocking shaft 5. In this case, the pin 21 of the operating lever 16 reaches the lower stopper 20.2 from the upper stopper 20.1 downward in the second elongated hole 20 without moving the left connecting rod 18, thereby unlocking the unlocking lever 12. Is limited. Since the backrest frame 3 is not adjusted until unlocking, the third elongated hole-pin joints 24 and 25 are not related at first.

続いて背もたれ枠３が、例えばそのばね予荷重又は使用者の手動操作により、例えば約９０°だけ前方へ図２に示す機能位置へ折り畳まれ、この機能位置が、例えば背もたれの上側がほぼ水平になるテーブル位置として、又はその後ろにある荷物室を延長する荷物位置として、又は中間の背もたれ部分においてケースとしても役立つ。  Subsequently, the backrest frame 3 is folded forward, for example by about 90 °, into the functional position shown in FIG. 2, for example by its spring preload or by a user's manual operation, so that this functional position is, for example, the upper side of the backrest being substantially horizontal. As a table position, or as a luggage position extending the luggage compartment behind it, or as a case in the middle backrest part.

この折り畳みの際、第３の連行機構の第３のピン２５はまず第３の長穴２４の上部ストッパ２４．２へ達し、続いて第３のピン２５が右側の連結棒２２を前上方へ引張るので、右側の鎖錠かぎ８がそのばね予荷重に抗して後上方へ揺動されて、構造部分１１を釈放する。それにより図２の前方へ折り畳まれる機能位置において、右側の鎖錠かぎ８が解錠されている。しかし車両座席１は、まずその前部せき止め軸線Ｂの周りに前方へは折り畳まれない。なぜならば、左側の鎖錠かぎ６は引続き構造部分１０の所で鎖錠されており、従って前方揺動を確実に阻止するからである。本発明によれば、使用者が座席上に居ないので、図２の示す鎖錠位置が、このような機能位置における座枠２の片側鎖錠だけで安全技術上問題のないことがわかる。  During this folding, the third pin 25 of the third entrainment mechanism first reaches the upper stopper 24.2 of the third elongated hole 24, and then the third pin 25 moves the right connecting rod 22 forward and upward. As it is pulled, the right locking key 8 is swung back upward against its spring preload to release the structural part 11. Thereby, the right locking key 8 is unlocked at the functional position folded forward in FIG. However, the vehicle seat 1 is not first folded forward around its front stop axis B. This is because the left locking key 6 is still locked at the structural part 10 and thus reliably prevents forward swinging. According to the present invention, since the user is not on the seat, it can be seen that the locking position shown in FIG. 2 is only a one-side locking of the seat frame 2 in such a functional position and there is no problem in terms of safety technology.

図２は、使用者が操作レバー１６を放した場合における機能位置を示し、係止調節器４はそのばね予荷重のため再びその鎖錠位置へ達することができる。それにより第１の連行機構の第１のピン１４は、解錠レバー１２を再び下方へ引張るので、第２の連行機構の第２のピン２１も、再び第２の長穴２０の上部ストッパ２０．１へ達する。  FIG. 2 shows the functional position when the user releases the operating lever 16, and the locking adjuster 4 can reach its locked position again due to its spring preload. As a result, the first pin 14 of the first entrainment mechanism pulls the unlocking lever 12 downward again, so that the second pin 21 of the second entrainment mechanism is again the upper stopper 20 of the second elongated hole 20. Reach 1

図２の機能位置から第３のせき止め位置へ車両座席１を調節するため、使用者は操作レバー１６を揺動する。図示した実施例では、このため操作レバー１６が下方へ破線で示す位置へ揺動されるので、解錠レバー１２に取付けられた第１の連行機構の第１のピン１４が、長穴１５の下部ストッパ１５．１からその上部ストッパ１５．２へ達し、即ち第１の長穴１５内に留まり、従って解錠レバー１２は揺動されない。しかし操作レバー１６の後部範囲で背もたれ軸線Ａの後に設けられる第２の連行機構の第２のピン２１は，図２において既に第２の長穴２０の上部ストッパ２０．１に当接しているので、操作レバー１６の下方への揺動の際、左側の連結棒１８が上方へ引張られ、これにより左側の鎖錠かぎ６をその解錠位置へ揺動させるので、左側の構造部分１０が釈放される。それにより図３において両方の鎖錠かぎ６，８が解錠されるので、使用者は続いて車両座席全体を前方へ例えば９０°又はそれ以上せき止め軸線（転倒軸線）Ｂの周りに揺動させることができ、そのため使用者は例えば座枠２をつかむことができる。  In order to adjust the vehicle seat 1 from the functional position of FIG. 2 to the third damming position, the user swings the operation lever 16. In the illustrated embodiment, the operating lever 16 is therefore swung downward to the position indicated by the broken line, so that the first pin 14 of the first entraining mechanism attached to the unlocking lever 12 is The lower stopper 15.1 reaches its upper stopper 15.2, i.e. stays in the first slot 15, so that the unlocking lever 12 is not swung. However, the second pin 21 of the second entrainment mechanism provided behind the backrest axis A in the rear range of the operation lever 16 is already in contact with the upper stopper 20.1 of the second elongated hole 20 in FIG. When the operating lever 16 is swung downward, the left connecting rod 18 is pulled upward, thereby swinging the left locking key 6 to its unlocked position, so that the left structural portion 10 is released. Is done. As a result, both locking keys 6 and 8 in FIG. 3 are unlocked, so that the user subsequently swings the entire vehicle seat forwards around a stop axis (falling axis) B, for example 90 ° or more. The user can then grasp the seat frame 2, for example.

前部せき止め位置からの戻り調節の際、使用者はまず車両座席１を後方へ起こすことができる。左側鎖錠かぎ６の構成に応じて、鎖錠かぎ６は自動的にはねて、左側の構造部分１０にかみ合う。そうでない場合、使用者はまず操作レバー１６を下方へ揺動させ、これにより左側の鎖錠かぎ６が左側構造部分１０へかみ合うのを可能にするので、図２の位置が得られ、この位置から使用者が、操作レバー１６の上方揺動により解錠レバー１２を揺動させ、従って両方の係止調節器４を解錠するので、使用者は続いて背もたれ枠３を上方へ図１の使用位置へ揺動させることができ、背もたれ枠３の右側に設けられる第３のピン２５が下方へ移動し、鎖錠かぎ８が右側の構造部分１１をつかむことによって、右側の鎖錠かぎ８も鎖錠が可能になる。  When adjusting the return from the front damming position, the user can first raise the vehicle seat 1 backward. Depending on the configuration of the left lock key 6, the lock key 6 automatically rebounds and engages the left structural part 10. If this is not the case, the user first swings the operating lever 16 downward, thereby allowing the left locking key 6 to engage the left structural part 10, so that the position of FIG. Since the user swings the unlocking lever 12 by swinging the operating lever 16 upward, and thus unlocks both the locking adjusters 4, the user continues to move the back frame 3 upward in FIG. It can be swung to the use position, the third pin 25 provided on the right side of the backrest frame 3 moves downward, and the locking key 8 grasps the right structural part 11, whereby the right locking key 8. Can also be locked.

従って３つの基本位置、即ち使用位置、機能位置及びせき止め位置の間の完全な調節が可能であり、そのために解錠ハンドルとしての操作レバー１６を操作しさえすればよく、場合によっては背もたれ枠３が前方へ折り畳まれるか、又は車両座席１全体がせき止め位置へ前方揺動される。  Therefore, complete adjustment between the three basic positions, ie, the use position, the function position and the damming position, is possible, and for this purpose it is only necessary to operate the operating lever 16 as an unlocking handle, and in some cases the back frame 3 Is folded forward or the entire vehicle seat 1 is swung forward to the damming position.

本発明による車両座席を鎖錠された使用位置において斜視図で示す。  1 shows a vehicle seat according to the invention in a perspective view in a locked use position. 左側の鎖錠かぎの解錠前に前方へ折り畳まれた機能位置（テーブル位置）にある車両座席を示す。  The vehicle seat is shown in a functional position (table position) folded forward before unlocking the left lock key. せき止め位置への続く調節のため左側の鎖錠かぎの続く解錠の際における車両座席を示す。  The vehicle seat is shown during subsequent unlocking of the left locking key for subsequent adjustment to the damming position.
